i've spent since March trying to get Verizon to correctly install DSL. they've wasted countless hours of my time (while collecting a paycheck at their end at the expense of the shareholders, of whom i am one) having me repeat the same procedures at my end, as if the problem were here. although two visits by Verizon technicians have confirmed that there is no problem at my end (not to mention that the service used to work flawlessly with the same equipment and configuration, but a different phone number).
obviously the problem is at Verizon's end. but, they refuse to address the real problem, whatever it might be, no doubt due to some bureaucratic imperative.
do yourself a favor: use cable for broadband net access (unless you want to be reduced to using NetZero, as i am doing at the moment).
